 //		Upstream Subcarrier Mask
+//			This attribute is a bit map representing upstream mask values for subcarriers 1 to 64. The MSB
+//			of byte 1 corresponds to subcarrier 1, and the LSB of byte 8 corresponds to subcarrier 64. Each
+//			bit position defines whether the corresponding downstream subcarrier is masked (1) or not masked
+//			(0).
+//
 //			Subcarrier number 1 is the lowest, and the number of xDSL subcarriers, upstream (NSCus) is the
 //			highest subcarrier that can be transmitted in the upstream direction. For [ITUT-G.992.3],
 //			[ITUT-G.992.4] and [ITUT-G.992.5], it is defined in the corresponding Recommendation. For Annex
